The invention discloses an automatic inflation/deflation hydro-pneumatic suspension device. The device comprises an axle A (1), an axle B (2), an axle C (3), a hydro-pneumatic suspension cylinder A (4), a hydro-pneumatic suspension cylinder B (5), a hydro-pneumatic suspension cylinder C (6), a check valve (9), an altitude valve A (7), an altitude valve B (8) and a gas source (10). When the device works, the height difference between the body of the hydro-pneumatic suspension cylinder A and the axle A (1) is more than a designated value, the attitude valve A (7) works at an inferior position, and the gas cavity of the hydro-pneumatic suspension cylinder A (4) emits gas to the atmosphere through the inferior position of the altitude valve A (7), so that the height difference between the hydro-pneumatic suspension cylinder A (4) and the axle A (4) is reduced. According to the automatic inflation/deflation hydro-pneumatic suspension device, the altitude valve A and the altitude valve B are provided with delay mechanisms to avoid frequent inflation and deflation for the hydro-pneumatic suspension cylinder A, the hydro-pneumatic suspension cylinder B and the hydro-pneumatic suspension cylinder C.
